Orion Launch Abort Motor Full-Scale Test Firing – Dry Run

Posted on by .

**Before I begin this post, let me warn you ahead of time that anything typed in another color other than black should be taken very lightly.  The Co-host has been color happy lately.**

The NASA EDGE team is in Promontory, Utah at the ATK Test Facility covering the Orion Launch Abort Motor full-scale test firing.  If you’ve never been to the test facility here’s what you see as you drive up to the main entrance.   I actually suggested that they refer to this event as a test hiring rather than a test firing.  I got nothing.

On November 20, NASA, ATK, and the Orion Project team will conduct the first full-scale test fire of the Launch Abort Motor for the Orion crew exploration vehicle.  A full-scale test like this has not been conducted since the days of the Apollo Program.  This test and earlier motor and component tests are paving the way for the Pad Abort-1 Flight Test scheduled for the spring of 2009. 

The Abort Motor stands over 17 feet tall, spans three feet in diameter and is equipped with a manifold that has four nozzles and turns the flow of the flames to create a pulling motion.

It is the primary motor in the Orion Launch Abort System (LAS).  The LAS will be able to pull the crew module to safety away from the Ares I launch vehicle in the event of an emergency on the pad or during the initial phase of ascent up to 300,000 feet.  Speaking of scale, this thing is huge.  It always seems smaller in the animations we use on the show.

In the picture above, the Abort Motor is fitted into the vertical test stand, with the nozzles pointed skyward.  The burn time for the test is five seconds.  I believe the flames exiting the nozzles may reach a height of 100 feet.  So we’ll see what happens during burn time.  Should be fun.

Today we had a chance to view the dry test run from the control room.  The dry run took about 45 minutes and involved a series of checks before a they ignited a small charge.   Import Dry Run Note: Remember not to drink a 64 oz. cafe latte before the test.  The script doesn’t call for bathroom breaks.

The team from ATK did a great job and I think everyone is ready for the test on Nov. 20.  Our coverage of the Abort Motor test is part of a NASA EDGE vodast we are doing on the Orion Launch Abort System.  Today we had a chance to conduct a few interviews for the vodcast.

WHAT!?!?!?!  Ron is a set therapist for ATK too!

Heather Angel is a propulsion engineer for Lockheed Martin.  She’s been with the company for a little over six months and has done an outstanding during her short tenure.  We expect big things from her in the years to come.

Did you notice the gradual increase in height from left to right?  For the record, we were on a slant.

We can’t produce a LAS vodcast without interviewing the head honcho for LAS, Barry Meredith.  Barry currently works at NASA Langley Research Center and has been with NASA for 40 years.  He works in the same directorate as me at Langley.  I can’t say enough about Barry.  He’s a straight shooter who knows how to get the job done.  Unfortunately Barry is leaving us in December and is retiring from NASA.  I am definitely looking forward to his retirement party.  And for his final act before retirement, Berry Meredith names Blair Allen as the nations top Medianaut with an emphasis in Magnetospherence!  If that doesn’t work, I can always emcee his retirement party.  I just bought a new karaoke machine.

Anyway enough rambling for one day.  Hey, the test firing is right around the corner and I think Ron is setting up the cameras.  We’ll be back to give you our take on the test firing and see if Blair’s hotdogs survived the burn.

All the best,
Chris

    Hello: My name is M. Guerard Putnam.

    Please forward this email to the appropriate NASA Departments for answers to the questions below.

    My concern was why terminate the Space Shuttle program until the Orion has been proved to be capable of servicing the Space Station. Also, to terminate the Shuttle in 2009, we will not have the ability to send cargo to the Station, or in case of emergencies we would have to rely upon the Russian Soyuz spacecraft which is more out of date than the Shuttle.

    Additionally, as an American, I am concerned with the Security aspect. One never knows the future intentions of the Russian Government, and I, as a Patriotic American, am concerned for our Crews, their safety, and reliability.

    From a personal standpoint, I was a close friend to the former Public Relations Director at Cape Canaveral, Bob Heiser. He would show us NASA films starting with the Mercury, through the Apollo missions.

    Having been in media and public relations, wouldn’t NASA need an ole goat like me assisting? I mention this, as I am only 62. However, I had to retire early due to spinal disc disease. However my mind isn’t affected. With whom would I be given due consideration?

    Might I add, that I was a Lake Logan which is located in the mountains of western North Carolina when the Apollo Moon missions were under study, and personally met Wernher von Braun, and took him fishing. I, also, met other notable NASA scientists, as well at Lake Logan.

    Finally, I was the Director of Human Resources at Stencel Aero Engineering in 1980, and we manufactured ejection seats for the Navy, and proposed an ejection system for the first test Space Shuttles.

    Although, I don’t have a degree in Aeronautical Engineering, I have an acute knowledge of NASA, and the interest.

    I apologize for this lengthy email, as it had two aspects; the Space Shuttle, and my interest in working for NASA in your media relations program.

    My address and phone numbers are as follows, but please answer my questions above,

    Regards from an American Patriot,

    Guerard

    “Actually this test was for the abort motor – which is being developed by ATK in Utah. The previous test was of the jettison motor – being developed by Aerojet in Sacramento, CA. The difference is that the jettison motor pulls the tower and the cover off on every flight that does NOT require an abort. The abort motor pulls off the Orion capsule in an actual abort.”
